Inadvertent lead malpositioning into the left ventricle (LV) is an uncommon complication of pacemaker lead implantation. It can have implications on clinical outcome due to ventricular dyssynchrony, and result in further complications such as thrombus formation with subsequent embolisation. This case study reports the clinical, electrocardiographic, plain film and echocardiographic findings of an 82-year-old male in whom the intravenous lead of a dual chamber pacemaker was unintentionally passed into the LV via an atrial septal defect. Inadvertent placement was discovered incidentally following the onset of atrial fibrillation (AF) 17 years later.
起搏器导线意外植入左心室（LV）是一种少见的并发症。由于心室失同步，它可能对临床结果产生影响，并导致进一步的并发症，如血栓形成和随后的栓塞。本病例报告了一位 82 岁男性的临床、心电图、平片和超声心动图表现，他的双腔起搏器静脉导线通过房间隔缺损意外植入 LV。17 年后，在发生心房颤动（AF）后，意外植入被偶然发现。
